COLIN MELVILLE, OF NEW YORK, N. Y.

M EGAPHONE.

SPECIFICATION forming part of Letters Patent No. 748,969, dated January 5, 1904.

Application filed July 24, 1903.

To a whom it may concern:

Be it known that I, COLIN MELVILLE, a citizen of the United States, and a resident of the city of New York, (City Island, borough of the Bronx,) in the county and State of New York, have invented a new and Improved Megaphone, of which the following is a full, clear, and exact description.

My invention relates to improvements in megaphones; and the object that I have in View is to produce a collapsible article which may be folded compactly to facilitate storage and transportation and at the same time may be easily and quickly adjusted in a way which prevents collapsing of its parts, so that the device can be used like an ordinary rigid megaphone.

Further objects and advantages of the invention will appear in the course of the subjoined description and the novelty will be defined by the annexed claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of my collapsible magaphone, showing the sections thereof adjusted in position for service. Fig. 2isalongitudinal sectional elevation through the megaphone in the position shown by Fig. 1; and Fig. 3 is a plan view, partly broken away, showing the sections of the megaphone adjusted one within the other and collapsed or folded compactly for storage and transportation.

As shown by the drawings, the megaphone consists of a plurality of sections, as A B, which are of collapsible construction in order that the section B may fold compactly within the section A. (See Fig. 3.) The section A consists of two members or pieces ca, which are united at their edges by pliable bindings 0, whereby the parts a a are permitted to fold laterally into a flat condition. The other section, B,consists of parts or members I) b, united by pliable bindings (1, so that the section B may fold laterally into a compact form, as shown by Fig. 3. The sections A B are of conical or tapered form, and the section B is smaller than the section A,in which it is adapted to fit telescopically, as shown by Fig. 2.

Serial No. 166,828. (No model.)

Each section may have its parts made of heavy cardboard, linoleum, leather, or any similar material, and the parts of each section are held together by bindings cor d, of fabric or suitable material. Each section has a tendency to collapse or fold, and the section B is adapted to slide within the section A when it is desired to pack or carry the article. The displacement or relative movement of the sections is limited by the employment of a pliable connection, which is represented in the d rawings in the form of a cord, tape, or the like at C. One end of this limiting cord or tape is attached to the section B, While its other end is fastened to the section Ain a suitable way, and this limiting-cord is of such length as to permit the section B to have an endwise and turning movement within the section A.

Assuming that the article is in its collapsed condition, as in Fig. 3, the section B is drawn outward and given a quarter-turn in order to bring its joints in a position at right angles to the joints of the sections A, the cord 0 limiting the movement of the sections relatively to one another. The turning movement of the section Bis advantageous, because it brings the two sections into such positions that the tendency of one to collapse is counteracted by the other section, whereby the sections are held in their proper positions when it is desired to use the article in the ordinary way. To fold the megaphone, the sections (or one of them) are turned so as to 'bring the joints into the same plane, whereupon the sections are free to collapse, and the section B can he slid into the section A within the limit of the length of the cord or tape 0.

I do not desire to strictly confine myself to the employment of any particular number of sections nor to the described means for limiting the relative movement of the sections nor to any particular material for making the sections, because these details may be varied within wide limits by a skilled constructor.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A megaphone consisting of collapsible sections foldable one Within the other and fitted telescopically together.

2. In a megaphone, a tapering member formed of sections of resilient material hinged together longitudinally at diametrically 0pposite sides, and means for holding said taporing member in circular form, said sections being adapted to normally fold into flat engagement With each other When released from said holding means.

3. A megaphone consisting of a plurality of tapering members each formed of sections longitudinally hinged together, each member being collapsible, and one member being turnable with respect to the other, whereby the tendency of the members to collapse is counteracted by the engagement of one m ember with the other.

4. Amegaphone consisting of taperingtelescopic sections each being provided With diametrically opposite longitudinal joints and collapsible, one section being turnable with respect to the other.

5. A megaphone consisting of tapering sections hinged together longitudinally to fold one upon the other, the sections being fitted telescopically one to the other, and means for limiting the relative movement of said sections.

6. Amegaphone,consistingoftaperingtelescopic sections, each formed of two pieces of resilient material provided with longitudinal hinges diametrically opposite each other, the hinges of two adjoining sections being in planes at right angles to each other.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

COLIN MELVILLE.
